Classic in style, this sapphire and diamond ring in platinum makes a unique diamond engagement ring. The three-stone ring design features a deep blue oval sapphire and two half-moon diamond sidestones.

This petite aquamarine eternity ring features an endless row of colour set in striking 18k white gold. While the style lends itself to grouping, aquamarines are a softer semi-precious gemstone not recommended for daily wear.

Blue Nile offers gemstone rings with choice of gemstones such as aquamarine, emerald, ruby, sapphire, and topaz. Look for gemstone rings that have vibrant, saturated colour. Most importantly, they should be translucent, not opaque. They should also be cut to maximise the beauty of the gemstone.
